Indeed, I have opteron and xeon mixed in same cluster.

improvement could be to check if flags are supported by host before starting or livemigrate.
I see a redhat bugzilla about this
https://bugzilla.redhat.com/show_bug.cgi?id=824987


But I think that enforce is enough for now,  the vm will stop when starting or the targetvm when we do live migration if flags are not supproted

I think that this is impossible to implement, because users may have different hosts 
inside one cluster. So It is hard to tell what selection we should allow.
